.3 Claims. (01. -92) This invention relates, as indicated, to paratusfor beating carpets or rugs.

A primary object of the invention isto provide an apparatus for beatingcarpets which does not require their removal from a horizontal or flatsupporting surface, and which, therefore, eliminates a great deal of theeffort and fatigue usually associated with such operations.

Another object of the invention is to provide apparatus which may betraversed over a carpet or rug in a horizontal position, and which iseffective to import a vibratory beating action to the carpet or rug,whereby dust and dirt are shaken out of the carpet or rug and find theirway through the interstices of the rug to the floor or surface beneaththe rug.

A further object of the invention is to provide apparatus of thecharacter described, which is effective to produce a sustained, strong,uniform, and highly efiicient beating action for the purpose described.

A still further object of the invention is to provide apparatus of thecharacter described, which is of extremely simple and ruggedconstruction,

which is virtually foolproof, and which can be manufactured at fairlylow cost.

Other objects and advantages of the invention will be apparent duringthe course of the following description.

In the accompanying drawings, forming a part of this specification, andin which like numerals are employed to designate like parts throughoutthe same,

Fig. 1 is a fragmentary side elevation of one form of apparatusembodying the invention, with portions thereof broken away in order to amore clearly show certain features of the con-' due principally tocentrifugal movement of the I apparatus over a carpet or rug which'is tobe beaten.

Mounted on the casing l, centrally-thereof, is A an electrically drivenmotor 4, having a vertically 2 A I unit 5 drives a verticalspindleorshaft 6. Removably secured'to theshaft 6, as by a nut 'l, is a disc .orplate 8, which is adapted to bejdriven or rotated by the motor 4. r

Secured to the lower surface of the disc or plate 8, adjacent theperiphery of the disc,,is a series of circumferentially-spaced swivelcasters '9, the peripheries of these casters being preferablytransversely rounded or crowned, as shown in Fig. 3, so as to facilitatemovement thereof onto a carpet. The axes of rotation of the frames orbrackets I 0, in which the casters are mounted are offset verticallyfrom the axes of rotation of the caster wheels, as is conventional inthis type ofcaster. The casters are preferably of f the ball bearingtype,so as to facilitate rotation of the brackets l0 about their axes ofrotation. In the use of the apparatus, the rugs or carpets are removedfrom the floor; and placed on afloor with the nap surface downward. Theapparatus is then propelled over the rug or carpet and the motor'4started. This imparts a rapid rotation to the disc 8, and-thereby to thecasters; As

the casters rotate with the disc, they are also rotated to some extentabout the axes of rotation of their brackets lil this latter rotationbeing casters caused by rotation of the disc. In any event, thisconjoint or compound rotation causes a vibration of the Whole apparatus,which vibration has a vertical componont which is effective to impart abeating action to the carpet or rug. This beating action is continuousand does not interfere with movement of the apparatus over the rug orcarpet, since the rollers 9 roll over the carpet, irrespective of theirposition in relation to the disc.

The theory as towhat causes this vibratory or beating action is notfully understood, but the fact remains that the vibratory or beatingaction is fairlystrong and constant, and is highly effective in beatingthe dust and dirt from the rug or carpet. The dust and dirt seep throughthe interstices of the rug or carpet and find their way to the floor,from which they may be removed after the carpet or rug has been lifted.

The number of casters employed may be varied, as well as their size andspacing. Thesevariations give rise to some variations in the vibratoryor beating action, but in all cases, the action has been foundsuflicient in intensity to remove substantially all of the loose dustand dirt from the carpet.

The extension 2 of the apparatus is preferably also provided withlaterally spaced wheels 3 II, which are not used during the beatingaction, but may be used to assist in propelling or moving the apparatusat other times, as by tilting the apparatus rearwardly until the wheelsII touch the ground and the casters 9 are clear of the ground.

It is to be understood that the form of my invention, herewith shown anddescribed, is to be taken as a preferred example Of the same, and thatvarious changes in the shape, size and arrangement of parts may beresorted to, without departing from the spirit of my invention or thescope of the subjoined claims.

Having thus described my invention, I claim:

1. In a carpet beating apparatus, the combination of a plurality ofcarpet-engaging means, each of said means being axially rotatable in avertical plane, a driving element axially rotatable in a horizontalplane, and swivel means pivotally securing each of said carpet-engagingmeans circumferentially to said element for orbital movement about theaxis of rotation of said swivel means, whereby each of saidcarpet-engaging means has a compound orbital movement about said swivelmeans and the axis of rotation of said element in response to carpettraversing movement of said element.

2. In a carpet beating apparatus, the combination of a roller supportingelement axially rotatable about a vertical axis, a plurality of roller51-.

brackets rotatably secured to said element in circumferentially spacedrelationship, each of said brackets being orbitally rotatable about an 4individual vertical axis, and a carpet engaging roller rotatably securedto each of said brackets for axial rotation about a horizontal axis,whereby each roller has swinging movement relatively to an individualvertical axis in response to traversal of a carpet by said element.

3. In a carpet beating apparatus, the combination of a roller supportingelement axially rotatable about a vertical axis, a plurality of rollerbrackets rotatably secured to said element in circiunferentially spacedrelationship, each of said brackets being pivotally movable about anindividual vertical axis, and a carpet engaging roller secured to eachof said brackets for axial rotation about a horizontal axis spaced fromsaid individual vertical axis, whereby each of said rollers has acompound orbital movement about said two vertical axes in response tocarpet traversing movement of said rollers.
